From eca8c2424171b6b6b2dcb0faa92dfddd1e3297d9 Mon Sep 17 00:00:00 2001 From: Ben Dooks Date: Mon, 28 May 2007 18:19:16 +0100 Subject: [ARM] 4412/1: S3C2412: reset errata fix The S3C2412 has an reset-errata where the clock may cause a glitch switching back to EXTCLK. We force a switch to EXTCLK before writing the reset register to force use of the CLKCON sync logic to properly switch. Fix problem reported by Matthieu Castet.
